Our Norms Of Testing & Quality Control

Quality aspect holds special importance in our every business strategy. We aimed at providing our customers with trouble free, safe and durable transformers. Our range of transformers is in conformation to ISS/ REC Standards. To offer quality transformers, our quality controllers conduct tests to conform IS: 1180 and IS: 2026 standards. We have also installed latest testing facilities and follow advanced testing techniques. This ascertains that the transformers are safe and easy to install. Further, we also issue a test certificate with every transformer having one year warranty. Moreover, we also conduct short circuit withstand test and impulse voltage withstand test to ensure that we deliver only quality range of transformers. These tests are conducted and arranged at C.P.R.I. Bhopal / Bangalore, Moradnagar/ ERDA Vadodra and other recognized laboratories. The other tests conducted by us are based on the following parameters:

* Dimension accuracy
* Tensile strength
* Corrosion resistance
* Ductibality
* Abrasion resistance
* Zero sequence current
* Insulation resistance
* Voltage ratio
* Induced over voltage test at double voltage and double frequency
* Vector group and polarity
* Separate source high voltage test of HV side and LV side
* No load losses, magnetizing current and impedance voltage
* Load losses and impedance voltage
* HV winding and LV winding resistance
* Measurement of temperature rise of winding and oil of transformers at full rated load
* Pressure and vacuum testing of transformer for permanent deflection of body
